I recall seeing a video about this but don't know if it was Amazon or not. They were using boxes not just to hold the items but, to become part of the structure in the truck while packing. That is, the boxes are sized to go together in somewhat even rows or stacks like bricks. The drift was that this reduces shipping damage by keeping things "just so" for the bulk of the delivery. The additional packaging is recyclable and damaged goods replacement kills a sale's profit and sometimes a customer's loyalty. It sounded good when they were saying it but, I'll bet that once it gets to the local distribution center all bets are off .
Any sufficiently advanced technology is indistinguishable from magic.
